The son of 11-term Rep. James P. Moran Jr. resigned from his father’s campaign Wednesday hours after an undercover video showed him discussing possible voter fraud with an activist posing as a campaign worker.

In the video, dated Oct. 8 and posted by conservative activist James O’Keefe, Patrick Moran does not explicitly advocate or condone the worker’s suggestion to cast ballots on behalf of 100 voters he says are unlikely to show up Nov. 6.

Moran, who appears not to know that he is being recorded, attempts to discourage the worker from carrying out the scheme, saying he should instead join get-out-the-vote efforts. But Moran, a campaign field director, also offers guidance on how to possibly skirt Virginia’s new voter identification laws. He also doesn’t tell the worker not to proceed with his plan.
